Hey, this is my first post here, and I have looked at other posts with the same BSOD, but none seem to have the solution to my issue. This Laptop is a Dell running WinXP. When trying to connect to the VPN via NetVanta (connected with a Verzizon air card), the BSOD appears with: Driver_irql_not_less_or_equal STOP 0x000000D1. another peculiar aspect of this BSOD is when it begins the physical memory dump, it says it is dumping physical memory to disk: 1 then disk: 2 then disk: 3 and so on continuously. I let it go up to 75 over the course of about 45 minutes before force shutting down. after looking at other posts, I saw that .dmp files can be used to diagnose the problem, and the last 4-5 are usually requested. well upon opening the mini dump folder, I only found one file, so it is attached (not sure how helpful that will be.) if you need any further information, just ask. Thanks!
